Table 2.

Effect of ‘age (first-year versus mature), ‘familiarity’ (familiar versus unfamiliar), ‘triad of the first crosser’ (first crosser triad versus other triad) on the individual latency to cross into the central chamber.

Fixed effect	Comparison	Estimate	2.5% CI	97.5% CI	P value
Intercept		8.599	7.821	9.382	0.001
Age	First-year versus mature	0.402	−0.590	1.218	0.085
Familiarity	Familiar versus unfamiliar	−0.036	−0.882	0.888	0.844
Triad of the first crosser	First crosser triad versus other triad	−0.073	−0.845	0.784	0.692
Random effect		Variance	± SD
Group		0.046	0.216
Day		0.282	0.531

Coefficients and 95% confidence intervals are presented. P values obtained with Tukey method adjusted for multiple comparisons. ‘Group’ and ‘day’ are fitted as random effects; we show the variance associated with them. The mealworms eaten by first crossers were excluded by the analysis in order to maintain data independence. Results are in the log (not in the response) scale.
